If the solubility of caffeine in water is 22 mg/mL at 20˚C and 66 mg/mL at 100˚C, and its solubility in dichloromethane is 140 mg/mL at 20˚C, calculate the partition coefficient for a water/dichloromethane mixture.
Homework Answers
The partition coefficient at 20 ° C is calculated:
K = Concentration in water / Concentration in dichloromethane = 22 mg / mL / 140 mg / mL = 0.16

Begin again by assuming 70. mg of caffeine is dissolved in 4.0 mL of water. This time, however, the aqueous solution will only be extracted ONCE with 6.0 mL of methylene chloride. Calculate the total milligrams of caffeine that can be extracted from the aqueous layer using this volume of methylene chloride. Caffeine has a distribution coefficient of 4.6 (K), between methylene chloride (CH2Cl2) and water.
